Description
Technical field
The present invention relates to a kind of awning film, specifically, relate to a kind of spectrophotometric spectra awning film that is used for agriculture green house of vegetables and preparation method thereof, belong to chemical technology field.
Background technology
When the chlorophyll of plant carries out photosynthesis, mainly rely on wavelength at the royal purple light of 400～480nm and the blood orange light of 600～700nm, the light that therefore is positioned at these two intervals helps photosynthesis of plants; And ultraviolet light in the daylight and green-yellow light are not absorbed substantially.At present, plastic greenhouse mainly relies on awning film raising canopy temperature to promote the growth of crop, and common awning film only is that the sunshine transmission after the decay is advanced in the plastic greenhouse, does not satisfy the growth of plant, and the disease and pest incidence of disease increases, and agricultural product quality is low.The main peak of spectrum just can be fallen chlorophyllous effective absorption region, thereby reach the purpose that strengthens light and effect only in the zone of 430～470nm, 600～680nm and the width of emission peak when big.Because the ultraviolet luminous energy inducing plant in 300～350nm zone produces disease and pest, so light conversion agent except that changeing green glow, preferably can be simultaneously changes into blue light or ruddiness with the ultraviolet light in 300～350nm zone.
In order to improve the utilization of crop to royal purple light and blood orange light, in recent years, very active to the exploitation of agricultural light conversion film and photothermal converting agent both at home and abroad, all kinds of agricultural light conversion films and photothermal converting agent constantly are born.Though the kind of these light conversion agricultural films and commentaries on classics light principle are not quite similar, can absorb in the sunlight harmful ultraviolet light of plant or the green glow useless but all have photosynthesis of plant, its conversion is launched the useful blood orange light of plant growth, royal purple light, thereby effectively illumination in the raising canopy, quicken its photosynthesis, promote its growth and characteristics precocious, that improve quality and increase production, increase income, above photothermal converting agent generally uses Eu
3+Compound is as rare-earth additive, though so Eu
3+Photothermal converting agent changes the optical efficiency height, and mostly that launches is Eu
3+Sharp peak, so the emission spectrum half width is narrow, Eu
3+The emission spectrum half width be 4nm, the matching of carrying out photosynthesis spectrum with crop is poor; The commentaries on classics optical attenuation phase of agricultural light conversion film is short, light conversion agent anti-ultraviolet ageing ability is very weak, there is serious decline in organic light conversion agent commentaries on classics optical property in the long-term use, fluorescent emission intensity generally can only reach the 10-30% of initial fluorescent emission intensity after being exposed to the sun 1 year in the open air, and degradation period has only some months during with the coexistence of hydroxyl utmost point group.
